The special effects, at the very least, are award-worthy. The movie came out over ten years ago and yet the effects are still top notch. It's one exciting movie too, of course. - BKAllmighty

The Contenders

11Star Wars Episode I: The Phantom Menace

I'm glad this one is here and not episodes II and III. I just can't stand Hayden Christensen's Anakin. I'll take Jar Jar Binks any day. - BKAllmighty

Agreed at least this film had some practical effects and some really good moments plus it has a very underrated score

In my opinion I think episode 3 is more underrated but it not have on the list so I vote for this.I hate jar jar at the first but when people keep hating it I feel like why people hate it so much much and I feel sad about jar jar for being most hate character in the world and now I just ok with it - Thirdwind

12Alien 3

If you get over the deaths of hicks newt and bishop there is plenty of good moments also this was David finchers first film

This was the second best alien series! what a shame!

132010: The Year We Make Contact

People don't appriviate this film just for being a sequel

14A.I. - Artificial Intelligence

All robotsI love futuristic cities at night time I want to go - SpencerJC

The best movie Disney ever made. By a long shot. - RockFashionista

16Galaxy Quest

17Armageddon

18Futuresport

19Serenity

Excellent series spawned an even greater movie.

20Lost in Space

21Mission To Mars

22Star Wars: Return of the Jedi

It's not that underrated... But it is a good film, it's just not as good as the first two ones.

23The Shadow

Underrated yes but not really sy fy in my opinion

24Supernova

great

25Star Wars: Revenge of the Sith

26Interstellar

27Minority Report

28Metropolis

29Snowpiercer

Shocking, thought provoking. Always love a movie that has a real message told through a hypothetical situation.

31Space Truckers

32Deep Star Six

34C.H.U.D.

35The Hidden

Suprised I'm not the only one who remembers this film

36Stalker

37Solaris (1972)

38Prometheus

39Space Camp

40Doom

41Star Trek: The Motion Picture

Underappriciated simply because of its slow pace dispite the fact that Alien and 2001 were slow paced but they get praise because critices say those movies did it better and most grew up watching Star Trek 2 which leads peolpe to unfairly hate this film

42Soldier

A contender for the most underrated sci fi movie of all time. Also maybe the best Kirt Russell movie of all time. If you are one of those "I don't like Kirt Russell" people, this is the movie that will make you say, "I don't like Kirt Russel, except in that Soldier movie." I felt that way about George Clooney in "From Dusk Till Dawn". I don't like George Clooney, except in that Dusk Till Dawn movie. But Soldier is nothing like DTD. It gives Kirt a role that, ironically, allows him to talk less and act more. He pulls it off perfectly in Soldier.

43Real Steel

Sure it has a pretty silly premise: boxing robots. But the film in my opinion is pretty intense. The robot fights were epic and I think this has to be Hugh Jackman's most underrated role. The child actor didn't do so bad either, the two of them had great chemistry. Definitely check this film out.
